Re: [ovirt-users] Fedora 21 as Ovirt (hypervisor) host

So I'm somehow lost if Fedora 21 is at least supported as hypervisor host. Anyone with deeper knowledge? The reason I'm asking: We are currently on FC20 + virt-preview and enjoy the feature of live merges. But with BZ1199182 (snapshot deletion bug) I guess we might need newer libvirt builds. With virt-preview for FC20 no longer in maintenance we would ony be on the save side with FC21. Markus Hi Markus, Dan Kenigsberg pushed changes to our automated build system for building VDSM on Fedora 21 for 3.5. I've not checked if he finished the porting of the required components into ovirt-3.5-snapshot, CCing him. As far as I know, there's willing to support Fedora 22 in 3.6 but no plans to support Fedora 21 either in 3.5 or in 3.6. As hypervisor host Dan can tell you better about VDSM plans for supporting Fedora 21, but I've not seen any feature proposal or bugs tracking the effort in that direction. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users -- Sandro Bonazzola Better technology.

Re: [ovirt-users] Communication errors between engine and nodes?
Hi Roel, You can change this setting in two ways. - you can update it in db directly as you stated (not recommended) - use engine-config -s vdsHeartbeatInSeconds=20 but prior to running this command you need to update config file /etc/ovirt-engine/engine-config/engine-config.properties with vdsHeartbeatInSeconds.type=Integer. This config value is not exposed by default. Thanks, Piotr On Mon, Mar 16, 2015 at 11:18 PM, Roel de Rooy rder...@motto.nl wrote: HI Piotr, Thanks for your reply!

Unfortunately log entries that you copied give me almost no information about nature of your issue. There are few things that we can do to understand what is going on with your setup. Heartbeat functionality provides means to detect whether we still have connection with a host. By default heartbeat timeout is set to 10 seconds but it can be modified by setting vdsHeartbeatInSeconds. In general whenever there are no incoming responses nor heartbeat frame is not received engine will invalidate the connection and will attempt to recover. If reconnection was successful you want see any other consequences of loosing single heartbeat. I would explore stability of your network so if the network is busy or you loose network packets from time to time this kind of entries in the log are expected. You can increase heatbeat value and see whether it will work better for your env. If you confirm that your network is stable we could explore the issue further by setting debug level logging for your engine to understand exactly how the messages are processes by a host and when we receive responses.

Re: [ovirt-users] Reinstalling a new oVirt Manager
Ok great, I can see the different storage that I want to import, but I can't
see the VMs on the un-connected pool.
So anyway I have to go further and import the storage domain passing the alert
message.
Am I right ?
No other way to see the VMs in SD :

Is there any command to verify if the storage domain contains VMs or not ?
You can execute this on one of your hosts.
# vdsClient -s 0 getStorageDomainsList
to get storage domain list, than
# vdsClient -s 0 getStorageDomainInfo domain UUID
for each of them till you identify the domain you are looking for.
You can also find there the pool UUID.
Than
# vdsClient -s 0 getVmsList pool UUID domain UUID
To get the list of VMs on that storage.

From my point of view that was about ovirt engine. So I'm somehow lost if Fedora 21 is at least supported as hypervisor host. Anyone with deeper knowledge? The reason I'm asking: We are currently on FC20 + virt-preview and enjoy the feature of live merges. But with BZ1199182 (snapshot deletion bug) I guess we might need newer libvirt builds. With virt-preview for FC20 no longer in maintenance we would ony be on the save side with FC21. Markus Hi Markus, Dan Kenigsberg pushed changes to our automated build system for building VDSM on Fedora 21 for 3.5. I've not checked if he finished the porting of the required components into ovirt-3.5-snapshot, CCing him. no, I did not touch any other package. As far as I know, there's willing to support Fedora 22 in 3.6 but no plans to support Fedora 21 either in 3.5 or in 3.6. As hypervisor host Dan can tell you better about VDSM plans for supporting Fedora 21, but I've not seen any feature proposal or bugs tracking the effort in that direction. Regardless of the ovirt builds http://resources.ovirt.org/pub/ovirt-3.5/rpm/fc*/ vdsm is built as part of any Fedora release and should be fully operational. The only problem is the amount of testing - and here you are most welcome to assist: yum install vdsm on your f21, and see if it flies. If you find a problem (be it a missing mom version or an operational bug) please report it here on on bugzilla.

[ovirt-users] Failed to read VM '[Empty Name]' OVF, it may be corrupted
Hi all, seing a strange issue here, I'm currently in the process of migrating from one ovirt setup to another and having trouble with the export/import process. The new setup is a 3.5 install with hosted engine and glusterfs the old one is running on a nightly release (not too recent) I have brought up an NFS export on the existing storage on the old setup, successfully exported a number of VM's and imported them onto the new system. However I came to move the last 4 VM's and am seeing an issue where after attaching the export storage to the new setup I see no VMs in the export storage to import and see this in the log: 2015-03-17 23:30:56,742 INFO [org.ovirt.engine.core.vdsbroker.irsbroker.GetVmsInfoVDSCommand] (ajp--127.0.0.1-8702-8) START, GetVmsInfoVDSCommand( storagePoolId = 0002-0002-0002-0002-0209, ignoreFailoverLimit = false, storageDomainId = 86f85b1d-a9ef-4106-a4bf-eae19722d28a, vmIdList = null), log id: e2a32ac 2015-03-17 23:30:56,766 INFO [org.ovirt.engine.core.vdsbroker.irsbroker.GetVmsInfoVDSCommand] (ajp--127.0.0.1-8702-8) FINISH, GetVmsInfoVDSCommand, log id: e2a32ac 2015-03-17 23:30:56,798 ERROR [org.ovirt.engine.core.utils.ovf.OvfManager] (ajp--127.0.0.1-8702-8) Error parsing OVF due to 2 2015-03-17 23:30:56,818 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ajp--127.0.0.1-8702-8) Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: Failed to read VM '[Empty Name]' OVF, it may be corrupted 2015-03-17 23:30:56,867 ERROR [org.ovirt.engine.core.utils.ovf.OvfManager] (ajp--127.0.0.1-8702-8) Error parsing OVF due to 2 2015-03-17 23:30:56,884 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ajp--127.0.0.1-8702-8) Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: Failed to read VM '[Empty Name]' OVF, it may be corrupted 2015-03-17 23:30:56,905 ERROR [org.ovirt.engine.core.utils.ovf.OvfManager] (ajp--127.0.0.1-8702-8) Error parsing OVF due to 2 2015-03-17 23:30:56,925 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ajp--127.0.0.1-8702-8) Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: Failed to read VM '[Empty Name]' OVF, it may be corrupted 2015-03-17 23:30:56,943 ERROR [org.ovirt.engine.core.utils.ovf.OvfManager] (ajp--127.0.0.1-8702-8) Error parsing OVF due to 2 2015-03-17 23:30:56,992 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ajp--127.0.0.1-8702-8) Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: Failed to read VM '[Empty Name]' OVF, it may be corrupted 2015-03-17 23:30:57,012 ERROR [org.ovirt.engine.core.utils.ovf.OvfManager] (ajp--127.0.0.1-8702-8) Error parsing OVF due to 2 2015-03-17 23:30:57,033 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ajp--127.0.0.1-8702-8) Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: Failed to read VM '[Empty Name]' OVF, it may be corrupted 2015-03-17 23:30:57,071 ERROR [org.ovirt.engine.core.utils.ovf.OvfManager] (ajp--127.0.0.1-8702-8) Error parsing OVF due to 2 2015-03-17 23:30:57,091 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ajp--127.0.0.1-8702-8) Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: Failed to read VM '[Empty Name]' OVF, it may be corrupted I've brought up new export storage domains on both the new and old cluster (and a seperate storage array for that matter) all resulting the same messages.

I have a Ovirt cluster with 6 VM hosts and 4 gluster nodes. There are two virtualisation clusters one with two nehelem nodes and one with four sandybridge nodes. My master storage domain is a GlusterFS backed by a replica 3 gluster volume from 3 of the gluster nodes. The engine is a hosted engine 3.5.1 on 3 of the sandybridge nodes, with storage broviede by nfs from a different gluster volume. All the hosts are CentOS 6.6. vdsm-4.16.10-8.gitc937927.el6 glusterfs-3.6.2-1.el6 2.6.32 - 504.8.1.el6.x86_64 Problems happen when I try to add a new brick or replace a brick eventually the self heal will kill the VMs. In the VM's logs I see kernel hung task messages.

Re: [ovirt-users] Power Management config on Ovirt
Hi, your VM was not migrated, because host node02 was not fenced. And host node02 was not fenced, because option Skip fencing if host has live lease on storage in your Cluster Fencing Policy is enabled. Prior fencing of the host we check its storage connection (renewal of its sanlock lease). You should see an alert about it in Events/Alerts tab in webadmin. So if you want to test VM migration on your cluster, have also block host connection to storage (and not only to engine). Also please take a look at Skip fencing on cluster connectivity issues option in Cluster Fencing Policy. If it's enabled and set for example to 50% and you have only two hosts in cluster, then your hosts won't be fenced at all due to it.

Hi, I don't know much about gluster configuration, but one of the following should work: 1. Turn off you host networking completely for example using /sbin/ifdown (you will need to access your node locally or using remote serial console, for example IPMI) 2. Block engine and all gluster hosts using iptables 3.

Hi, prior to the test I would check this: - Data Center status is Up - All hosts status is Up - All storage domains status is Up - VM is running If this is valid, you can start your fence testing.

But is still does the same. Node01 is shutdown. Do you think RHEV + gluster storage will not have this issue. What storage do you recommend?

Turn off you host networking completely for example using /sbin/ifdown (you will need to access your node locally or using remote serial console, for example IPMI) 2. Block engine and all gluster hosts using iptables 3. Disable Skip fencing if host has live lease on storage option in Cluster Fencing Policy and block connection between host and engine (in this case storage connection won't be checked prior to fencing) Martin Perina - Original Message - From: Renchu Mathew ren...@cracknell.com To: Martin Perina mper...@redhat.com Cc: Piotr Kliczewski piotr.kliczew...@gmail.com, users@ovirt.org Sent: Tuesday, March 17, 2015 2:26:29 PM Subject: RE: [ovirt-users] Power Management config on Ovirt Martin, Yes, I need to test the VM migration. So can you please tell me how to block the host connection to storage? It is a glusterfs volume with distribute option as below.
